Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a system for real-time detection and control of processes. Background Technology

[0002] In battery recycling extraction processes, it is necessary to analyze the metal components in the extract. Current processes primarily rely on metal analyzers for single-component analysis of the extract, directly using the resulting data, which is insufficiently accurate in terms of metal composition. Utility Model Content

[0003] The purpose of this invention is to provide a system for real-time process monitoring and control, so as to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a system for real-time detection and control of a process, comprising: a component analysis module for real-time detection of the target metal concentration in the extract; a colorimetric detection module for real-time detection of the transmittance and turbidity of the extract; and a control module for acquiring the target molecular concentration, transmittance, and turbidity of the extract, and using the transmittance and turbidity to correct the target metal concentration to obtain the final metal concentration.

[0005] This technical solution has at least the following beneficial effects: by using the transmittance and turbidity of the extract detected by the colorimetric detection module, the range of metal concentration values ​​in the extract can be predicted, and the target metal concentration detected by the component analysis module can be corrected accordingly, thereby obtaining more accurate final metal concentration data and improving the anti-interference ability of metal concentration detection.

[0006] As a further improvement to the above technical solution, the component analysis module includes a first peristaltic pump, a first filter, a second peristaltic pump, a first dilution tank, a third peristaltic pump, and a component analyzer connected in sequence. The input end of the first peristaltic pump is connected to a first extraction tank from which the extractant needs to be extracted. The first dilution tank is connected to an injection pump for injecting pure water for dilution. The component analyzer is used to detect the target metal concentration in the diluted extractant. This prevents the extractant from adhering.

[0007] As a further improvement to the above technical solution, a second dilution tank is connected between the third peristaltic pump and the component analyzer. A fourth peristaltic pump is connected to the second dilution tank for introducing pure water for dilution. This secondary dilution of the extractant ensures that the metal concentration in the extract is within a detectable range.

[0008] As a further improvement to the above technical solution, a multi-way switching valve is connected between the second dilution tank and the component analyzer. This multi-way switching valve is used to introduce pure water into the second dilution tank for cleaning. A fourth three-way valve is connected to the input end of the fourth peristaltic pump. This allows for the cleaning of the second dilution tank.

[0009] As a further improvement to the above technical solution, a multi-way switching valve is connected between the third peristaltic pump and the component analyzer. This multi-way switching valve is used to introduce standard solutions into the component analyzer and to introduce manually extracted solutions into the component analyzer. The multi-way switching valve is connected to a fifth peristaltic pump for introducing manually extracted solutions. Standard solutions can be introduced into the component analyzer for standardized detection, and manually extracted solutions can also be introduced into the component analyzer for detection of manually extracted extracts.

[0010] As a further improvement to the above technical solution, a circulation loop is also connected between the first peristaltic pump and the first filter. The circulation loop is connected to the extractant and is equipped with a first regulating needle valve for adjusting the flow rate. Excess extractant is returned to the extractant via the circulation loop, thereby ensuring that the required amount of extractant is extracted evenly for testing.

[0011] As a further improvement to the above technical solution, a first three-way valve is connected between the input end of the second peristaltic pump and the first filter, and a second three-way valve is connected between the output end of the second peristaltic pump and the first dilution tank. A third three-way valve is connected to the first three-way valve. Alcohol or pure water is introduced through the third three-way valve, and the introduced alcohol or pure water can be discharged through the first and second three-way valves after passing through the second peristaltic pump, thus flushing the second peristaltic pump and the pipelines at both ends.

[0012] As a further improvement to the above technical solution, a fifth three-way valve for introducing compressed gas to drive the extraction liquid and / or a sixth three-way valve for discharging waste liquid are connected between the third peristaltic pump and the component analyzer. The compressed gas is introduced into the output end of the third peristaltic pump through the fifth three-way valve, allowing the compressed gas to drive the extraction liquid and ensuring sufficient power to transport the extraction liquid to the component analyzer over a longer distance for detection. The liquid in the first dilution tank can be discharged through the sixth three-way valve, allowing for cleaning of the first dilution tank and the third peristaltic pump.

[0013] As a further improvement to the above technical solution, the colorimetric detection module includes a colorimeter and a sixth peristaltic pump, a second filter, and a flow cell connected in sequence. After the sixth peristaltic pump draws extract from the second extraction tank, the extract passes through the second filter and the flow cell before flowing back into the second extraction tank. The colorimeter is used to detect the transmittance and turbidity of the extract in the flow cell. Using a flow cell design to detect the color of the target extract can accurately detect the transmittance and turbidity of the extract, and at the same time, can clearly identify potential impurity precipitation or emulsification risks.

[0014] As a further improvement to the above technical solution, it also includes an extraction regulation module for adjusting the extractant and an acid concentration detection module for real-time detection of acid concentration in the extractant. The color detection module is also used to identify the risk of impurity precipitation or emulsification and generate risk data. The control module is also used to acquire the acid concentration, risk data, and target extractant regulation parameters of the extractant in real time, and control the extraction regulation module to perform real-time reagent regulation of the extractant based on the acid concentration, target metal concentration, transmittance and turbidity, risk data, and target extractant regulation parameters. By monitoring the real-time detection parameters of the extractant, such as metal concentration, acid concentration, transmittance and turbidity, and other parameters, and controlling the extraction regulation module to perform real-time reagent regulation of the extractant based on these parameters, such as increasing or decreasing the extractant and adjusting the acid solution, closed-loop intelligent control of the extraction process is achieved, significantly improving the automation level of the production process.

[0026] Reference Figure 1-5 The system for real-time process monitoring and control includes a component analysis module 10, a colorimetry detection module 70, an acid concentration detection module 80, an extraction adjustment module 81, and a control module 90.

[0027] The component analysis module 10 includes four pumps, a first filter 12, a first dilution tank 14, and a component analyzer. The four pumps are a first peristaltic pump 11, a second peristaltic pump 13, a third peristaltic pump 16, and a syringe pump 15. The input end of the first peristaltic pump 11 is connected to a first flow stabilizing tube, which is located in the first extraction tank 18 to be tested. The output end of the first peristaltic pump 11 is connected to the inlet of the first filter 12. The filter outlet of the first filter 12 is connected to the output end of the second peristaltic pump 13. The output end of the second peristaltic pump 13 is connected to the inlet of the first dilution tank 14. The outlet of the first dilution tank 14 is connected to the input end of the third peristaltic pump 16. The output end of the third peristaltic pump 16 is connected to the detection end of the component analyzer 17.

[0028] The input end of the syringe pump 15 is connected to pure water, and the output end of the syringe pump 15 is connected to the inlet of the first dilution tank 14, so that the syringe pump 15 can introduce pure water into the first dilution tank 14 to dilute the extract for the first time.

[0029] The component analysis module 10 uses a first peristaltic pump 11 to draw the extractant solution from the first extraction tank 18 to the first filter 12 for filtration, and then uses a second peristaltic pump 13 to introduce it into the first dilution tank 14 for mixing and dilution. The diluted extractant solution is then introduced into the component analyzer 17 via a third peristaltic pump 16 for real-time detection, thereby obtaining the target metal concentration. The component analyzer 17 is an inductively coupled plasma atomic emission spectrometer (ICP-AES). By detecting the diluted extractant solution using the component analyzer 17, the concentration of the target metal, such as Li, can be obtained. + Co 2+ Ni 2+ Fe 2+ Mg 2+ concentration.

[0030] Furthermore, a circulation loop 40 is connected between the first peristaltic pump 11 and the first filter 12. One end of the circulation loop 40 is connected to the inlet of the first filter 12 or the other outlet of the filter without the filter element, and the other end of the circulation loop 40 is connected back to the first extraction tank 18. A first regulating needle valve 41 is installed on the circulation loop 40. The first regulating needle valve 41 is used to regulate the flow rate of the extract back to the first extraction tank 18, thereby controlling the amount of the extract to be tested passing through the filter element in the first filter 12, so as to control the amount of the extracted extract according to the detection requirements.

[0031] Furthermore, the system in this embodiment is also equipped with a first three-way valve 50, a second three-way valve 51, and a third three-way valve 52. The first port of the first three-way valve 50 is connected to the filter outlet of the first filter 12, the second port of the first three-way valve 50 is connected to the input end of the second peristaltic pump 13, and the third port of the first three-way valve 50 is connected to the second port of the third three-way valve 52. The second port of the second three-way valve 51 is connected to the output end of the second peristaltic pump 13, and the first port of the second three-way valve 51 is connected to the inlet of the first dilution tank 14.

[0032] The first and third ports of the third three-way valve 52 are connected to alcohol and pure water, respectively. By adjusting the first three-way valve 50, the connection between the first and second ports is broken, and the connection between the second and third ports is opened. By adjusting the second three-way valve 51, the connection between the first and second ports is broken, and the connection between the second and third ports is opened. By adjusting the third three-way valve 52, the connection between the first and second ports is broken, and the connection between the second and third ports is opened. This allows pure water to flow through the third three-way valve 52 to the first three-way valve 50, and then into the second peristaltic pump 13 for cleaning. After being discharged from the output end of the second peristaltic pump 13, the cleaning wastewater is discharged through the second and third ports of the second three-way valve 51, facilitating the cleaning of the second peristaltic pump 13, its input end, and the pipeline connected to the input end. Similarly, by adjusting the third three-way valve 52, the connection between the second and third ports is broken, and the connection between the first and second ports is opened, allowing alcohol to be introduced to clean the second peristaltic pump 13.

[0033] Furthermore, a fifth three-way valve 60 is connected between the output end of the third peristaltic pump 16 and the component analyzer 17, and a sixth three-way valve 61 is connected between the fifth three-way valve 60 and the component analyzer 17.

[0034] The fifth three-way valve 60 has a first PTFE tube connected to its first port. Compressed gas, such as compressed nitrogen, is introduced into the first port of the fifth three-way valve 60 through the PTFE tube. The first PTFE tube is equipped with a first pressure regulating valve and a first two-way solenoid valve. The second port of the fifth three-way valve 60 is connected to the second port of the sixth three-way valve 61, and the third port of the fifth three-way valve 60 is connected to the output of the third peristaltic pump 16. The first port of the sixth three-way valve 61 is connected to the detection end of the component analyzer 17.

[0035] When the diluted extract to be tested is delivered to the component analyzer 17 via the third peristaltic pump 16, compressed gas is introduced from the fifth three-way valve 60 and pushes the extract to be tested to be delivered to the component analyzer 17, ensuring that the extract has sufficient power to be delivered to the component analyzer 17, which is a longer distance away, to complete the detection.

[0036] Furthermore, the second three-way valve 51 is adjusted to close the connection between the first and second valve ports, the fifth three-way valve 60 is adjusted to close the connection between the first and second valve ports, and the sixth three-way valve 61 is adjusted to close the connection between the first and second valve ports and open the connection between the second and third valve ports. When the syringe pump 15 introduces pure water into the first dilution tank 14, the first dilution tank 14 can be cleaned. The wastewater after cleaning passes sequentially through the third peristaltic pump 16, the fifth three-way valve 60, and the sixth three-way valve 61, and is discharged from the third valve port of the sixth three-way valve 61, thereby achieving the cleaning treatment of the first dilution tank 14, the third peristaltic pump 16, and the fifth three-way valve 60.

[0037] A second dilution tank 21 is connected between the first valve port of the sixth three-way valve 61 and the detection end of the component analyzer 17, and a multi-way switching valve 30 is connected between the second dilution tank 21 and the component analyzer 17.

[0038] The first port of the sixth three-way valve 61 is connected to the inlet of the second dilution tank 21, and the outlet of the second dilution tank 21 is connected to the second port of the multi-way switching valve 30. The first port of the multi-way switching valve 30 is connected to the detection end of the component analyzer 17. The second dilution tank 21 is also connected to a fourth peristaltic pump 22. The output end of the fourth peristaltic pump 22 is connected to the inlet of the second dilution tank 21, and the input end of the fourth peristaltic pump 22 is connected to a fourth three-way valve 31. The second port of the fourth three-way valve 31 is connected to the input end of the fourth peristaltic pump 22, and the third port of the fourth three-way valve 31 is connected to pure water.

[0039] By opening the connection between the second and third valve ports in the fourth three-way valve 31, pure water is introduced into the second dilution tank 21 through the fourth peristaltic pump 22, thereby enabling secondary dilution of the test extract and ensuring that the metal concentration in the test extract is within the detectable range.

[0040] By opening the first and second valve ports of the multi-way switching valve 30 and closing the other valve ports, the secondary diluted extract can be introduced into the component analyzer 17 for detection.

[0041] The third port of the multi-way switching valve 30 is connected to pure water. By adjusting the multi-way switching valve 30 to connect the third and second ports and close the other ports, pure water can be introduced into the second dilution tank 21 for cleaning. The water is then discharged as cleaning waste liquid through the first port of the fourth three-way valve 31 via the fourth peristaltic pump 22. This allows for the cleaning treatment of the second dilution tank 21.

[0042] Furthermore, the fourth port of the multi-way switching valve 30 is connected to a standard solution, which is a solution with a standard metal concentration. By adjusting the multi-way switching valve 30 to open the fourth and first ports and close the other ports, the standard solution can be introduced into the component analyzer 17 for calibration and other operations.

[0043] Furthermore, the fifth port of the multi-way switching valve 30 is connected to a fifth peristaltic pump 32. The input end of the fifth peristaltic pump 32 is connected to the manually extracted test solution, and the output end of the fifth peristaltic pump 32 is connected to the fifth port of the multi-way switching valve 30. By adjusting the multi-way switching valve 30 to open the fifth and first ports and close the other ports, the manually extracted test solution can be introduced into the component analyzer 17 for detection via the fifth peristaltic pump 32. Therefore, it can be understood that the multi-way switching valve 30 is at least a five-way valve.

[0044] The colorimetric detection module 70 includes a sixth peristaltic pump 71, a second filter 72, a flow cell 73, and a colorimeter 74. A second flow stabilizer is installed at the input end of the sixth peristaltic pump 71, and the second flow stabilizer is inserted into the second extraction tank 75 to allow the sixth peristaltic pump 71 to draw the extractant to be tested. The second flow stabilizer is installed on the second extraction tank 75 via a stainless steel terminal clamp connector.

[0045] The output of the sixth peristaltic pump 71 is connected to the inlet of the second filter 72, and a second regulating needle valve 76 for adjusting the flow rate is connected between the output of the sixth peristaltic pump 71 and the inlet of the second filter 72. The filter outlet of the second filter 72 is connected to one end of the flow cell 73, and a third regulating needle valve 77 for adjusting the flow rate is connected between the filter outlet of the second filter 72 and one end of the flow cell 73. The other end of the flow cell 73 is connected back to the second extraction tank 75, thus forming a circulating loop structure. A colorimeter 74 is used to detect the transmittance and turbidity of the extract in the flow cell 73. The colorimeter 74 can dynamically analyze the transmittance and turbidity of the extract through a multi-wavelength LED light source and a CMOS image sensor array, and identify the risk of impurity precipitation or emulsification to generate risk data.

[0046] Both the first filter 12 and the second filter 72 are filters with self-cleaning capabilities.

[0047] In addition, the second filter 72 is connected to a second PTFE tube, which is equipped with a second pressure regulating valve and a second two-way solenoid valve. After closing the second regulating needle valve 76, pure water is introduced into the second PTFE tube, allowing it to flow sequentially through the second filter 72, the third regulating needle valve 77, the flow tank 73, and finally into the second extraction tank 75, thus completing the cleaning process. After the pure water cleaning is complete, instrument air can be introduced to dry the interior.

[0048] The acid concentration detection module 80 operates on the same principle as the colorimetry detection module 70, both consisting of a sixth peristaltic pump 71, a second filter 72, and a flow cell 73 connected in sequence. The acid concentration detection module 80 includes an acid concentration meter, used to detect the target acid concentration in the flow cell 73 in real time, such as the concentration of organic acids in the organic phase or the concentration of H2SO4 or HCl in the aqueous phase. Furthermore, the acid concentration detection module 80 also includes a temperature compensation module, which includes a thermometer that measures the temperature of the extract in the flow cell 73 and obtains temperature data, correcting the acid concentration measured by the acid concentration meter using this temperature data. Additionally, the second filter 72 in the acid concentration detection module 80 incorporates an ion-selective filter membrane to isolate interference from non-target ions.

[0049] It should be noted that the first extraction tank 18 and the second extraction tank 75 are the same extraction tank, which includes multiple extraction chambers. The sampling points of the component analysis module 10, the colorimetry detection module 70, and the acid concentration detection module 80 can all be distributed in the required multiple different extraction chambers. In other embodiments, depending on the different detection requirements, the first extraction tank 18 and the second extraction tank 75 can also be two related extraction tanks.

[0050] The control module 90 is communicatively connected to the component analysis module 10, the colorimetry detection module 70, and the acid concentration detection module 80, respectively. The control module 90 obtains real-time target molecule concentration, transmittance, and turbidity of the extract by controlling the operation of the component analysis module 10, the colorimetry detection module 70, and the acid concentration detection module 80 in real time. It then uses the transmittance and turbidity of the extract to correct the target metal concentration, thereby obtaining the final metal concentration.

[0051] The extraction control module 81 includes multiple pipelines connected to the extraction tank to be tested. Each pipeline is connected to a pneumatic diaphragm regulating valve. These pipelines are used to add acid solutions, alkaline solutions, organic solutions, metal solutions, and extractants to the extractant in the extraction tank. By controlling the opening degree of the pneumatic diaphragm regulating valves in the multiple pipelines, the extraction parameters of the extractant in the extraction tank, such as the concentration of metal ions, the concentration of organic acids, and the content of impurities, can be adjusted.

[0052] The control module 90 is configured with target extractant adjustment parameters via an external input device. Based on the final metal concentration, risk data, and the target extractant adjustment parameters, the control module 90 calculates and generates control parameters. The extraction adjustment module 81 receives these control parameters and performs real-time reagent control of the extractant in the extraction tank. Alternatively, the control module 90 can calculate and generate control parameters based on the target metal concentration, transmittance, turbidity, risk data, and the target extractant adjustment parameters. If an embedded AI chip is used to run a multi-parameter fusion algorithm, real-time process adjustment commands can be generated to regulate the extractant, such as extractant replenishment and acid adjustment. This enables real-time, high-precision monitoring of key process indicators such as metal ion concentration, acidity, and color during the extraction process.

[0053] Based on mechanistic knowledge and historical data, LSTM time-series prediction models and reinforcement learning optimization algorithms can be used to accurately predict the efficiency of the extraction process. Combined with model predictive control decision theory, the control system in the linkage control module 90, such as the DCS system, can automatically adjust the flow valve and the dosing pump to form a "sensing-prediction-control" closed loop, reduce manual intervention, improve response speed, and realize the optimized control of the extraction process based on digital twins.

[0054] This approach leverages data and machine learning to construct dynamic control models for process parameters, enabling closed-loop intelligent control of the extraction process. This not only significantly improves the automation level of production processes but also allows for real-time visualization of process status through digital twin technology, effectively ensuring product quality consistency and stability. It provides reliable technical support for the intelligent upgrading of hydrometallurgical processes. The target extractant adjustment parameters can be specific process parameters or continuously updated learning models.

[0055] For example, in the nickel extraction process, the first extraction tank 18 is sampled and tested by the component analysis module 10 to detect Li. + Concentration range 0.1-0.5 g / L; Detection of Ni + Concentration range 0.1-20.0 g / L; Detection of Mg2+ + The concentration range is 0.0-0.2 g / L. The acid concentration detection module 80 analyzes the concentration of organic acids in the organic phase or the concentration of H2SO4 or HCl in the aqueous phase through specific spectral energy absorption, and the temperature sensor compensates for fluctuations of ±0.1℃. In the colorimetry detection module 70, when the transmittance at 630 nm wavelength decreases by 10%, the automatic addition of demulsifier is triggered. The real-time detection data from the component analysis module 10, the colorimetry detection module 70, and the acid concentration detection module 80 are transmitted to the control module. The control system included in the control module, such as a DCS system, adjusts the extraction ratio (O / A) in real time through APC advanced control algorithm software and PID algorithm to maintain the optimal distribution coefficient.

[0056] Example of PID parameters:

[0057] "With the proportionality coefficient Kp = 0.6, the integral time Ti = 90s, and the derivative time Td = 10s, the extraction rate increased from 95% to 99.5% after adjustment."

[0058] DCS Communication Protocol:

[0059] Supports Modbus TCP / IP or OPC UA protocols with a response latency of ≤200ms. Data acquisition via communication enables the collection of various process parameters and advanced optimization control.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
